Chrysanthemum plant named ‘GG GTCHA 05’

ABSTRACT

A new and distinct  Chrysanthemum  plant cultivar is disclosed, characterized by medium-size daisy type inflorescences, consistent flowering response to short days, blooming consistently after 52 days of short day length, bronze yellow ray florets with dark red underpetal, and a moderate branching habit.

Latin name of the genus and species: Chrysanthemum morifolium.

Variety denomination: ‘GG GTCHA 05’.

BACKGROUND OF THE INVENTION

The new cultivar ‘GG GTCHA 05’ was originated from a cross made by Leo Van Zanten in a planned breeding program in January 2001 between the male parent ‘Miramar’ (U.S. Plant Pat. No. 7,469) and the female parent ‘Lucky Time’ (U.S. Plant Pat. No. 10,777). The new cultivar was discovered and selected by Leo Van Zanten in August 2001 in Oxnard, Calif.

Asexual reproduction of the new cultivar ‘GG GTCHA 05’ by vegetative cuttings in Oxnard, Calif., and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘GG GTCHA 05’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘GG GTCHA 05.’ These characteristics in combination distinguish ‘GG GTCHA 05’ as a new and distinct Chrysanthemum cultivar:

-   -   1. Medium-size daisy type inflorescence;     -   2. Yellow-bronze ray florets with dark red underpetal;     -   3. Moderate branching habit; and     -   4. Blooming consistently after 52 days of short day length.

Plants of the new cultivar ‘GG GTCHA 05’ are similar to plants of the male parent variety, ‘Miramar’ in most horticultural characteristics, however plants of the new cultivar ‘GG GTCHA 05’ are taller than the male parent. Also, the shape of the ray florets of the new cultivar are oblanceolate compared to the spoon-shape florets of ‘Miramar.’ Further, ‘GG GTCHA 05’ have smaller inflorescences and more orange-yellow ray florets than the male parent.

Plants of the new cultivar ‘GG GTCHA 05’ are similar to plants of the female parent variety, ‘Lucky Time’ in most horticultural characteristics, however plants of the new cultivar ‘GG GTCHA 05’ are taller than the female parent. Also, the male parent has anemone-type flowers compared to the daisy form of the new cultivar ‘GG GTCHA 05’. Further, the new cultivar has yellow ray florets compared to the light pink ray florets of the female parent.

In comparison to the commercially available variety ‘Bronze Cherie’ (U.S. Plant Pat. No. 9,702), ‘GG GTCHA 05’ are taller than that of the comparable variety. Additionally, the new variety ‘GG GTCHA 05’ has larger inflorescence diameter. Further, the new variety ‘GG GTCHA 05’ has more yellow ray florets compared to the yellow-orange ray florets of ‘Bronze Cherie’. Finally, ‘GG GTCHA 05’ has more green foliage than the yellow-green foliage of the comparable variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘GG GTCHA 05’ grown in a 6.5-inch container. Five cuttings were used in the pot, planted late October and grown in a greenhouse. The colors are as nearly true as is reasonably possible in a color representation of this type.

-   Disease resistance: Neither resistance nor susceptibility to     diseases or pests has been observed in this variety. -   Drought tolerance/cold tolerance: Flowering plants are hardy to low     temperatures about −2° C. Non-flowering plants are hardy in the     approximately range of 3° C. to −6° C., depending upon duration of     cold and amount of moisture in the soil. With adequate water plants     are hardy to a high temperature of 45° C. -   Fruit/seed production: Commercially, this plant is not used or     observed in a stage where seeds would be produced. Therefore, seed     production has not been observed.
